This pdf is 3 pages long, with about a page devoted to SRD and editorial, so let's check out this item!

Oathbreaker is an axiomatic guisarme that was originally crafted for a fanatic of the Sanguine Covenant, seeking to root out any pagan priests and subsequently falling from grace. The guisarme also grants 2 to saves vs mind-influencing effects, can cast 3/day cure serious wounds or remove disease, 1/day take control of a summoned creature and even potentially postpone the repercussions of violating a codex/code of conduct for some time.

The pdf comes with a page of item-cards.

Conclusion:
Editing and formatting are terribly flawed for such a short pdf. There is one sentence on the second page (which also includes editorial SRD - lot of wasted toner/printer for printing out a couple of lines)that is either missing or a combination of a cut-copy-paste-job gone wrong. The crunch also fails to put spell-names in italics and also at which caster-level these spell-like abilities work, rendering this weapon unusable as intended. Which essentially renders an otherwise nice weapon with an interesting ability unusable as presented. The pdf has a beautiful artwork, layout adheres to a 2-column standard and the pdf has no bookmarks. In the end, though, the cool ideas can't really save this item, since it just doesn't work as intended. Taking the shortness of the pdf into account, I'll have to settle for a final verdict of 1.5 stars, rounded down to 1 for the purpose of this platform.
